Through the above scheme, the water inlet a and the water outlet pipeline 500 do not occupy the installation space of the water tank 400, which is beneficial to enlarging the volume of the water tank 400.

In an alternative embodiment, the number of the water tanks 400 may be one, or the water tank 400 includes a first tank 410 and a second tank 420, and the first tank 410 and the second tank 420 are provided to correspond to both sides of the mop assembly 300. Specifically, as shown in fig. 4, the mop assembly 300 includes a first mop 310 and a second mop 320, the first case 410 may be disposed corresponding to one side of the first mop 310 away from the second mop 320, and the second case 420 may be disposed corresponding to one side of the second mop 320 away from the first mop 310, such that a vacant space is reserved between the first case 410 and the second case 420, and other function modules may be disposed in the vacant space to expand other functions, and further, the concentration degree of components inside the cleaning robot is improved, and the space utilization rate is improved.

The first tank 410 has a first water containing space, the second tank 420 has a second water containing space, and both the first water containing space and the second water containing space are communicated with the water inlet a and the water outlet b. Alternatively, the first tank 410 may communicate with the second tank 420, in which case one of the first tank 410 and the second tank 420 is provided with a water inlet a, and the other is provided with a water outlet b; the first tank 410 may not be communicated with the second tank 420, in which case, the first tank 410 and the second tank 420 are provided with a water inlet a and a water outlet b. In a word, compared with the scheme that the cleaning robot is provided with the water tank 400, the water containing volume of the cleaning robot is increased, and the endurance mileage is improved.

In an alternative embodiment, the first tank 410 may not be communicated with the second tank 420, and the first tank 410 and the second tank 420 are both provided with a water inlet a and a water outlet b, and each water outlet b is communicated with the water outlet pipeline 500, however, as a result, the number of the water inlets a and the water outlets b is large, and water needs to be added to the first tank 410 and the second tank 420 respectively, which causes inconvenience in adding water.

In an optional embodiment, the water tank 400 further includes a first bottom wall and a first top wall 422, the first side wall 421 is located between the first top wall 422 and the first bottom wall, the water outlet b is located on the first top wall 422, a distance between the air outlet c and the first top wall 422 of the water tank 400 may be greater than a distance between the air outlet c and the first bottom wall of the water tank 400, that is, the position of the air outlet c is lower, so that when the water level in the water tank 400 is higher, that is, the water level is higher than the position of the air outlet c, the air outlet c cannot function, the balance between the internal air pressure and the external air pressure of the water tank 400 is broken, and the water in the water tank 400 is difficult to flow out.

Therefore, in another embodiment, the distance between the air outlet c and the first top wall 422 of the water tank 400 is smaller than the distance between the air outlet c and the first bottom wall of the water tank 400, i.e., the position of the air outlet c is higher, so that even if the water level is higher, the air outlet c is not submerged by water, and the air outlet c continues to function, keeping the internal air pressure and the external air pressure of the water tank 400 balanced. In this embodiment, the second tank 420 includes a first side wall 421, a first bottom wall and a first top wall 422, the air outlet c is flush with the first top wall 422, and the position of the air outlet c is higher than the highest point of the communicating part 430, so that the internal air pressure and the external air pressure of the second water tank 400 can be kept balanced even when the water level is higher than the highest point of the communicating part 430.

In an alternative embodiment, the water tank 400 further includes a peripheral plate 440, the peripheral plate 440 is opposite to the first sidewall 421, and the first sidewall 421 and the peripheral plate 440 form a water containing chamber 450, the water containing chamber 450 communicates with the exhaust port c, and the water containing chamber 450 is provided with a first opening 451, the first opening 451 communicates with the external atmosphere, that is, the inside of the water tank 400 communicates with the external atmosphere through the exhaust port c and the first opening 451, ensuring the internal air pressure and the external air pressure of the water tank 400 to be balanced. The cleaning robot has a generally cylindrical structure, and since the water tank 400 is located at an edge position, the peripheral plate 440 is configured in an arc-shaped structure to fit the shape of the cleaning robot, and in consideration of the requirement of mold opening, the first side wall 421 of the water tank 400 has a flat plate structure, which results in a gap between the first side wall 421 and the peripheral plate 440, and the water containing chamber 450 is naturally formed by the gap between the two. Alternatively, as shown in fig. 5, the first opening 451 may be provided at the bottom of the water containing chamber 450, the first opening 451 being directly opposite to the ground, or the first opening 451 being communicated with the external atmosphere through a pipe.

Although the waterproof and breathable film can prevent water in the water tank 400 from leaking outside to some extent, part of the water in the water tank 400 enters through the air outlet c and is stored in the water containing cavity 450 over time, and in this case, the water in the water containing cavity 450 can be discharged out of the cleaning robot through the first opening 451, so that the water cannot flow to other positions to affect functions of other parts.
